The use of voice-over in film and video is far-reaching, both in its creative application and practical use. This may come as bad news to those of you who find the experience of listening to your own recorded voice unpleasant or even surreal, as many do. In fact, the phenomenon is so common it has earned its own name – voice confrontation!
But the good news is that your videos could benefit greatly if you can overcome your voice confrontation and figure out how to write, record, and edit good voice-overs. In this article, we’ll be looking at 3 main things:
- What is voice-over?
- When to use it (as well as when not to)
- Most importantly, how to produce high-quality voice-over without breaking the bank.
What voice-over is and when to use it
While the concept of voice-over is likely familiar to most of us, defining it and looking at examples could be a good way to get inspiration for your own voice-over projects. Voice-over refers to the use of recorded speech placed over associated visuals but without including visuals of the speaker. So then, it is typically a separate audio asset that you incorporate into your video that is recorded with an emphasis on audio quality. This is as opposed to occasions where you might extract dialogue from a video clip to use over other footage, such as when performing split edits (J-cuts or L-cuts). So, in what instances might you expect to find voice-over? Perhaps its most iconic use, though admittedly becoming dated, is in trailer narration. Most famously of all must be the “in a world…” genre of trailers of the 1980s-2000s, voiced by the now legendary Don LaFontaine.
This specific approach to editing trailers is now considered a little corny and is only used ironically these days. However, it still demonstrates the crucial voice-over principle, which can be applied in contemporary work to great effect. This principle communicates a lot of information without boring the audience and adds more drama and interest to what is seen. If not in trailer narration, you will certainly find voice-over used for this purpose elsewhere.
Still within the narrative context, for example, voice-over is often used in film or TV where you need to convey large amounts of information in a limited time, often to establish details that the rest of the story relies on. In the example below from X-Men: Days of Future Past (2014), we hear voice-over, which makes sense of the visuals we are seeing, but that also adds more than the visuals could imply on their own. It is also used to build excitement and curiosity in the viewer and establishes some of the key themes explored in the film.
Additionally, we are seeing voice over used more and more on social media, tutorial-based content, and it’s a great way to increase the accessibility of our videos.
Having said all this, in the narrative context, I would still only recommend using voice-over in this way sparingly. A generally agreed-upon rule of thumb is “show, don’t tell” when it comes to conveying plot, character or theme. Generally, if you can put across information through visuals alone, it creates a more engaging and enjoyable experience for the viewer than spoon-feeding it to them. With that in mind, here are some thoughts on when voice-over, in the film/TV context, can be a great addition:
- When the information you need to convey cannot be communicated visually. The opening 5 minutes of Dune (2021) is a good example.
- When voice-over is truly the more engaging method of communicating information to the viewer. You could argue this is the case in Goodfellas (1990) (think, “As far back as I can remember, I always wanted to be a gangster“)
- When voice-over adds something unique and creative that the film/TV show would otherwise lack. Consider the voice-over that introduces “The Dude” in The Big Lebowski (1998)
One of the most powerful features of voice-over is its capacity to breathe life and energy into the visuals they accompany. They do so with the human connection of having a real person talk to you, the audience, throughout. Of all the video creators out there, not many rival Casey Neistat in the ability to creatively combine visuals and sound to craft highly entertaining stories, all with a personal touch and unique style. In the example below, voice-over is used extremely creatively to give the visuals greater meaning. It allows each clip to contribute towards a singular idea despite being so different.
So, having now looked at examples of voice-over in action, let’s summarize the benefits of good voice-over:
- Conveying information
- Adding drama/interest/creativity
- connecting and adding meaning to different components of a video
How to create a voice-over
Let’s work out the process of creating a voice-over to ensure that your end result does justice to your creativity and that (ideally) you don’t break the bank. You can record voice-overs in the traditional way, or one cost-effective and increasingly popular method is using AI.AI voice generators
Synthesized voices are nothing new, but technology is constantly evolving, meaning that computer-generated voices now sound uncannily human rather than robotic and that AI is opening up enormous possibilities when it comes to speech. Just as ChatGPT produces text based on learning from huge inputs of data, AI voice generators are also trained on vast quantities of spoken words. This enables them to learn what human voices actually sound like, how we all vary in tone, pitch, and pace, that we have differing accents, and that our emotions can have an impact on our delivery, too. The greater the library of human voices an AI voice generator trains on, the more realistic it will sound. When trained, an AI voice generator produces audio files using text-to-speech technology. It breaks down the text into its phonetic components and synthesizes them into words and sentences. An AI voice generator that includes natural language processing technology will be able to produce more natural-sounding audio. These generators have been programmed to reflect nuances in speech and language, for example, how we tend to raise our pitch toward the end of a sentence when asking a question. The pace of improvement around AI technology means that voice-overs are sounding increasingly human and can include subtleties around accents and emotionTraditional voice-over recording
Choosing a microphone
This is a big decision and probably the part of this process that could risk costing you the most money. Fortunately, many budget options exist that still record sound to a good standard. At the end of this article, you’ll find a table outlining some of the most popular options at different price points. In the meantime, we’d recommend reading DJ Pangburn’s comprehensive article on the best microphone choices depending on the kind of audio you need to capture. Before moving on, however, here are a few of the most important things to factor into your decision:- Consider the polar pattern of your microphone. This basically refers to the space around your microphone that it will pick up sound from. For voice-over, you will likely want a unidirectional – or “cardioid” – microphone rather than an omnidirectional one. This ensures you capture only the sound in front of the mic (your voice) rather than everything in the whole room.
- Most mics are either dynamic or condenser—what makes one type more suitable than the other could be quite specific to you. Condenser mics are typically considered best for voice-over as they pick up more detail in the voice. Still, at the same time, they can pick up more unwanted sounds from your environment as well. Dynamic mics will be more forgiving here. However, if you have ideal audio recording conditions, your result may not be as rich as a condenser mic in the same situation.
- Studio microphones are most commonly used for voice-over work, though shotgun microphones can also be suitable.
- Think about all the kinds of audio you’ll want to record for your videos, not just voice-over. If you’re on a tight budget, you may find a mic suitable for various contexts to be better than an excellent voice-over mic that’s not great for anything else (like capturing audio on a film set).
Preparing the room
The treatment of the room you aim to record a voice-over it will probably make more of a difference to the quality of your audio than nearly any other factor. Perhaps you’re lucky enough to have access to a studio or a soundproof room fitted with acoustic panels. In all likelihood, you won’t, but that’s ok. You can do plenty to a room at no additional expense to dramatically improve audio quality. This can broadly be thought of as a twofold process.- Soundproofing: This is doing what you can to prevent outside, unwanted noises from entering your recording. If you are recording in your own house, you’ll hopefully get away with just choosing the quietest room possible, shutting doors and windows, and hanging material over them (blankets, rugs, etc.). However, if thin walls, noisy neighbors, nearby traffic, etc., are serious issues, you may need to consider other recording locations.
- Â Sound treatment: Unlike soundproofing, sound treatment favorably manipulates sound quality within a room (including sound from the intended source). When you begin speaking, a portion of that sound will travel directly into your microphone (direct noise). Still, most of it spreads around your room, bounces off walls and other objects, and then enters the microphone (reflected noise). With voice-over especially, you generally want to minimize reflected noise and maximize direct noise for a clean sound. To do this, you could take away hard objects in the room and cover any remaining ones with absorbent material.
Writing a script
Before having fun with the purely technical side of voice-over, it’s vital to think through your script before recording. Stream of consciousness and off-the-cuff voice-over may work for certain types of videos, but as discussed earlier in the blog, voice-over is at its best when it complements and enriches the visuals it accompanies. This is much harder to achieve without planning. Of course, how you go about this will be a unique and creative decision of your own, but here are a few areas to think about. As helpful as voice-over is at communicating information, you can only get away with it if it is interesting. Try to write concisely so as not to waste the listener’s time, but also take advantage of the human element voice-over provides to add some flair to your writing. Since voice-over is made to go alongside visuals, it’s good to write with the viewer’s experience in mind. Since you know the viewer will be both listening and watching, you can let the visuals do some of the talking. In other words, if the visuals communicate something already, then saying it in voice-over is like repeating yourself. The link below begins with a specific example of what I mean in a brilliant video essay by Nerdwriter (Evan Puschak) on the film Logan (2017). While I highly recommend watching the whole video as it’s a masterclass on voice-over writing in general, this specific example is interesting.
When referring to an approach to superhero storytelling, he says, “I wonder if you can think of a superhero film that might fall into that category” while showing an iconic clip from the Batman franchise. Notice that he doesn’t need to use voice-over to explain that Batman is such a film because he knows the audience will make that connection on their own. This gives the video a real cohesiveness that shows the creator put thought into communicating their ideas.
Delivery
Assuming you are the voice for your voice-over (though, of course, you don’t have to be), you may want to practice how you’ll deliver your carefully written script. From a technical standpoint and in terms of audience reception, you will want to find consistency in your pace and volume. That’s not to say you can’t speed up and slow down or speak louder and quieter for dramatic effect. Still, you want to establish a default pace and volume to return to so the viewer isn’t taken out of the experience by noticing shifts in these things. Clarity is another area to be conscious of. You want to strike a delicate balance between sounding clear and understandable without sounding like you are reading word-for-word from a script (even though you probably are). Try to make sure you are in a comfortable position when recording, which should also help with volume consistency. Perhaps the most helpful tip is to practice. Record samples and, assuming you have overcome your voice confrontation, listen back to them and analyze whether you sound natural!Post-production
In video, you can fine-tune so many variables (exposure, color, framing, etc.) that even a bad shot from the camera could become a good-looking shot after editing. With audio, while there are just as many, if not more, fine-tunable adjustments available, they generally rely very heavily on the original recording’s standard. If you have bad background noise, the volume is too low, a lot of unwanted reflected noise, or inconsistent volume, you can do things to minimize the prominence of these issues in the post. However, you are unlikely to ever get a crisp, clean finished product. Assuming you do have clean audio, what else can you do to improve it even further? This isn’t the kind of question that has a one-size-fits-all answer. The kind of editing that your audio needs depends on several factors:- The microphone
- The environment in which the audio was recorded
- Even the recorded voice.
Voice-over vs AI voice generator for creators and businesses
If you are uncertain whether you should stick with a traditional voice-over or try an AI-generated voice-over, let’s look at the pros and cons of both.- Natural voice-over pro: Precision—You can be certain that a human will deliver a voice-over according to your preferred intonation, cadence, accent, and pronunciation.Â
- Natural voice-over pro: Ethics – no uncertainty over how the AI was trained, about deep-fakes, and no concerns over job displacement.
- AI voice-over pro: Speed – a script can be fed into an AI voice generator, and an audio file can be produced quickly.
- AI voice-over pro: Cost—There’s no need to hire a voice actor or purchase or loan expensive equipment.
- AI voice-over pro: Flexibility – the same script can be translated and delivered in different languages without the need for multiple voice actors.
Wrapping up
So, we’ve taken a close look at voice-over, when to use it, and how to produce it. Hopefully, you’ll have the tools and understanding to add it professionally to your next project. With these tips and new technology like AI voice generation, you’ll be in a good place creatively and technically to ensure your voice-over maximizes your video’s potential.Was this article helpful?
